我在这里试图做的是,我已经使用populateView显示了一个列表视图,我想使用searchview
对其进行过滤,但是我不确定如何做到这一点。任何帮助或建议都将是很棒的,因为我是Firebase和android的新手。我还附加了用于显示列表视图的代码。
MainMenu.java
public void makeItem ()
{
lv = findViewById(R.id.listView);
db = FirebaseDatabase.getInstance().getReferenceFromUrl("https://vsem-inventory.firebaseio.com/ItemList");
FirebaseListOptions<ItemObject> options = new FirebaseListOptions.Builder<ItemObject>()
.setLayout(R.layout.content_main_menu_list)
.setQuery(db,ItemObject.class)
.build();
mAdapter = new FirebaseListAdapter<ItemObject>(options) {
@Override
protected void populateView(@NonNull View v, @NonNull ItemObject model, int position) {
final TextView tvAmount = v.findViewById(R.id.amount);
final TextView tvName = v.findViewById(R.id.name);
final TextView tvSerial = v.findViewById(R.id.serialNo);
final TextView tvSupplier = v.findViewById(R.id.supplierName);
final ImageView more = v.findViewById(R.id.more);
ImageView statusimg = v.findViewById(R.id.status);
Drawable paidIcon = v.getResources().getDrawable(R.drawable.succes);
Drawable lateIcon = v.getResources().getDrawable(R.drawable.late);
tvName.setText(model.getProductName());
tvSerial.setText(model.getSerialNo());
tvAmount.setText(model.getQuantity());
tvSupplier.setText(model.getModel());
final String Remarks = model.getRemarks();
final String cat = model.getCategory();
if(model.getQuantity().equals("0"))
statusimg.setImageDrawable(lateIcon);
else
statusimg.setImageDrawable(paidIcon);
more.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v) {
String serialNo = tvSerial.getText().toString();
String itemName = tvName.getText().toString();
String quan = tvAmount.getText().toString();
String supplier = tvSupplier.getText().toString();
showMenu(itemName,more,serialNo,quan,supplier,cat,Remarks);
}
});
}
};
lv.setAdapter(mAdapter);
}
